To all ufhom 'it may concern:

'Bc it known that I, JuAx'LAsoLois, a citizen of Canada, residing etMoline, in the county of Rock lsltmd and State of Illilmvoinvented nevand useful lm provemcnts in (talig-Flows, of which the following' is a'specification.

This invention relates to gang plows, and it has for its object toproduce a riding and `improved construction and which shnll bethoroughly useful and effective in opera-tion.

A- specinl object of the present invention is-to provide a constructionwhereby. it n rock or similar obstruction shall be encountered bytheplon..tlie nose ot the plow will be ytilted in :in upward direction,causing the. plow to ride over the obstruction Without danger ofbreakage or injury, .fitter which the parts may be replaced inipcsition'or operation.

Further objects ot the invention are to provide a, simple and improvedconstruction whereby necessary andv desirable adjustments device may beconveniently effected. A

' ll'vith these and other ends in View which will readily appear as thenature of the inventionis better understood, the same consists ipl theimproved consti-notion and novel arrangement and combination of partswhich Weill be' hereinafter fully described nd 'particularly pointed outin the claims.

In the accompanying drawings lisis been Villustrated a simple andpreferred form ot' the invention, 1t being, however, understood that nolimitationis-,nccessaiily mode to the precise structural details-thereinexhibited,

Fig. 8 is a perspective detailviewof one of the sector supporting brackets. Fig. 9 is a perspectivedetail view ci' one of the sectors. Fig. l0 is a perspective detail Viewof one of the draft slides. v

The axle l supports uprights Q, 2 which nre connected at their upperends by. a cross bar 3, said uprights and cross our constituting whatwill be known as the iront treme. The main frame B is composed of sidemembers 4, 4 bolted upon and extending rearwardly from the uprights 2.The side members -l e nre of unequal-length, and said side members areprovided nt their rear ends with inwardly extending brackets 5, 5 whichare connected together by a longitudinal brace The bracket 5 forms nstep or offset. in advance of the rear end ot the fiume where thebracket 5 is located, this construction being adapted to a gang plowcomposed of two umts. Nhen additional units it' to be employedadditional ofsets or brecltets iure to be formed in the :trame structureto accommodate such additional units.

Brackets including vertically disposed sleeves 8 are suitably bolted orotherwise secured upon the ends of the axle, said sleeves affordingbearings 'for the shafts 9 provided at their loiver cnds Withspindles l)upon which the transporting Wheels 11 are journnled. The shafts 9 nrevertically slidable in the sleeves 8, and said shafts are provided :ittheir upper ends with collars l2, each having a notch 13 wherein is iv`oted one end of a link lA, the other en of which isjpivotally connectedwith one arml cie-s lever l5 ulcrumed on the main frame B and having astop member 16 engaging n rack segment 17, whereby the parts will beretained in 'adjusted position. it will be obvious that by meons'of 'theadjusting. le-

"rers 15 the transporting -Wlicels may be raised or lowered with respectto the frame, thus enabling one of sold wheels to be usedv as a lendt-vheel and the other ns a furrow Wheel.r While for tri-importation thewheels therewitliyl said shafts or uprights cing extended. through thecross bar 3 of the `front .y frame and provided with nuts 24 wherebythey arr.y firmly secured in position. The

forwardlyfextending arms 20 of the plates 19 are pryided withlongitudinal slots 25, and adjacent to said slots are upstandmg flangesor .gdes 26 between which the draft slides 27 guided, said slides beingprovided witl'` bolts 28 extending through the slots and constitutingstops to 'limit the movement ef the slides-"27. The slides 27 are alsoprovided with reinforcing. ribs 8O which are transversly apertured forthe passage of bolts 3l'.

livotally .mounted on the curved bracket 21 of each plate 22 is atoothed sector 32 having at its front end an anti-friction wheel 33andzterminating at its rear end in a beak 34.

.Connected with each sector adjacent to the rear end thereof a chain`35which 'is guided forwardly along the under .arcuate edge of the sectorin engagement with the teeth of the latter, said chain being connectedatits forward end, preferably by means of an elongated rod or link 3G,with one end of the transverse connecting bol-t 31, whereby the saidchain is connected with the 27.`

Slidablyniounted on cach of the shafts or uprights 23 is a sleeve 37having rearwardly extending arms 38, one of which is provided with alateral fia-nge 39. The' beam 40 of a plow unit is pivotally securedbetween the arms 38, and the parts are so arranged and assembled thatthe anti-fric 'tion wheel 33 at the front end of a sector 32 willnormally engage the underside of the flange 39 near the front end kof`the latter. Pivoted on the plow beam 40 is a latch member 41"-having atits lower/end a beveled hook 42 engaging the correspondingly beveledbeak 34 at the rear end of a sector Bolted on the beam 40 adjacent tothe downturned port-ion which' forms the plow carrying standard 43 is arearwardly extending .arm or bracket 44 having a Tl1ead 45. The plowbeam also supports a block 46 carrying an adjustable hook bolt 47 whichis connected by a strong helical spring 48 with a hook 49 pivotallyassociated with the'latch Y vented. Bolted member 41, said hook memberbeing mounted on the latch member intermediate its fulcrum and the upperend thereof which is connected by a link 50 with en adjusting lever51.'.I

' It will be seen from the foregoing descrip .tion that when the partsare assembled for operation, the beak 340i the sector 32 engages the hook 42 of the latch member 414V the contacting faces of the beak and thehook being slightl beveled, as shown, to enable the beak to becomedisengaged from the hook by the exertion of a predetermined degree oftension which may be governed by regulating the tension of the spring 48by means of the adjustable hook bolt 42. The spring 48 must be sucientlvstrong to resist the ordinary strain of, plowl Should this strain becomegreatly exceed as when an obstruction is encountered, the beak of thesector will become disengaged from the hook, and the sector will turnaboutl its axis,l causing the anti-friction wheel 33 to exert upwardpressure against the' flange 39, thereby tilting the front end of theplow beam, together `with the sleeve 37 in -an upward direction, andthrowing the nose or point of the plow unity in an upward direction,causing it to leave the ground until the obstruction has been safelypassed, after which the Aspring 48 by the use of theadjusting lever 51,may be again placed under tension, thus enabling the beak of the sectortobe again placed in engagement with the hook 42. The draft is appliedto the slides 27 by mea-ns of a. connectingbar 52 having means such as aclip 53 for the attachment of the draft.

The bracket membersl 5, 5 at the rear end of the main frame are eachprovided with lugs 54 between which and the T-head 45 of the rearwardlyext-ending arm 44 of one of the plow beams 40 is guided in such a manneras to permit vertical'movement to take place while lateral movement ispreor secured on the rear sides of the brackets 5, 5 are segment racks55 upon which hand levers 56 are fulcrumed each of said levers beingprovided at its lower end with a forwardly extending arm 57 having alaterally extending supporting hook 58. Pivoted on the fulcrum of eachof the levers 56 is a rod 59 which is loosely supported ou one of thesupporting hooks 58, the front end of such rod being connected b v alink 60 with .the T-head 45 of one of the arms 'or brackets 44 extendingiarwardly from the plow beams. Each of t e hand levers 56 has a stopmember 61 engaging the segment rack 55 for the purpose of retaining theparts in adjusted position. It will be `seen that this construction notonly enables the plow 'units to be independently raised or lowered forthe purpose of f are peee to engage the. 'lower 'ef manpnating the'same.
